This lamp has a four pin connector with the pins facing INSIDE the lamp, not facing outside, like other lamps. The outside diameter is 5.5 inches, the tube diameter is a T4, which means it's 1/2 inch diameter. The 6400 degree color temperature simulates bright daylight illumination.  It is used in mirrors such as the BE-116 (BE116), BE-116T (BE116T), BE-121 (BE121), BE-122 (BE122), BE-123 (BE123), BE-125 (BE125), BE-125MB (BE125MB) and others.
The collar with the electrical connector is designed to swivel 25 degrees in either direction.  There may be a small separation between the top and bottom halves of of the plastic collar, due to variation in the tubing diameter.  Neither of these has any impact on the operation of the lamp.
